【选型】国产可精确调节电流输出的配电开关SGM2553,可用于电网数据记录设备的USB限流设计需求
在电子电力产品中一些用于热插拔的端口设计限流保护措施是很有必要的,常见的USB口就是典型的可热插拔端口,它广泛应用于各类计算机设备上。像电网数据记录设备产品就有USB端口用于工作人员连接外设通信操作,考虑到保护设备内部电路安全需要在USB口附近设计上限流保护电路。
今天推荐圣邦微电子(SGMICRO)这款可精确调节电流输出的配电开关SGM2553,它符合USB限流要求,在输出负载超过电流限制阈值时,采用恒流模式将输出电流限制在安全水平。当驱动输出电压高于输入电压时,内部反向电压比较器将禁用电源开关,以保护开关输入侧的设备。
SGM2553的工作电压范围在2.5V至5.5V,能提供高达1.5A的连续负载电流,常用的USB端口基础供电要求也是5V/1A左右满足要求。另外通过调节ILIM位置的外部电阻值可提供100mA至1.7A的可编程电流限制阈值,这样客户可以根据产品设计需求设置合适的限流保护值。
当端口与外设接插拔时往往有瞬间的电流浪涌可能会对设备造成损害,而SGM2553通过控制电源开关的上升和下降时间可以最大限度地减少打开/关断期间的电流浪涌,从而保护设备内部电路以及外设。
SGM2553目前有TDFN-2×2-6L和SOT-23-6这两种常见环保封装形式,而且其外围电路简单,基本适用大部分场景的设计要求。而且SGM2553也不仅限用于USB端口的限流设计,在其他有类似需求的限流配电开关电路中同样可以适用。
